SPINDLE-BEARING FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 349,826, dated September 28, 1886.l

Application filed January 2, 1885. Serial No. 151,801. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, JosErn E. TYNAN, of' Paterson, in the county of Passaic and State of New Jersey, have invented anlmprovement in Spindledcarings for Spilining-Machines, of which the following is a specification.

In spilining-machines the bobbin is sometimes heavier on one side than the other, and hence when revolving under high speed there is an undue vibration, because the spindle-axis is not the center of gravity on which the parts would spin if unconfined. To accommodate this condition sometimes existing in spindles and bobbins the bolster has been supported so as to yield, but the pull of the belt has been resisted by the same yielding support; hence thespindleassu mes an inclined condition under the pull of the belt, and the yielding support being thus partially compressed at one side does not actuniformly in yielding to the vibrations of the spindle-axis due to the center of gravity of the bobbin not coinciding to the axis of the spindle.

My improvement consists in the combinations of devices hereinafter set forth, by which the spindle is supported, oiled, and allowed to vibrate if the bobbin is not true.

In the drawings, Figure 1 is a vertical sect-ion showing the rail, the spool, the pulley, the bolster-case, and the bolster in section, eX- cept the lower end ofthe bolster, which is in elevation, the spindle being i n elevation. Fig. 2 is an inverted section at thelinexx, Fig. l. Fig. 3 is an elevation of the spindle and a vertical section of the rail, bolster-ease, and bolster, except the lower end ofthe bolster, which is in elevation. Fig. 4 is an elevation of the spindle and section of the bolster,bolster-case, and spindle-rail. Fig. 5 represents the tubular bolster-spring as forming also a lining for the bolster. Fig. 6 is an inverted plan of the tubular bolster shown in Fig. 4.

In my application No. 131,105, filed May 12, 1884, the oil-eup is above the spindle-rail, and the tubular bolster-case passes through the rail and is secured by a nut, the bearing of the bolster is near the pulley,and there is a springsupport for the lower end of the bolster. My

present invention, therefore, does not consist, broadly, in the combination ot' these devices. The spindle-rail is shown at A, the oil-cup ing l.

at B, the bolster-case at G, and the nut at D, s ecuring the bolster-case and oil-cup to the rail.

The spindle E is provided with a tubular sleeve, F, that extends down around the outside of the bolster-ease C, and terminates at its lower end with the pulley I-I. This sleeve F is tapering in its exterior shape, and the bobbin G is bored out to fit over the same, 1n order that it may pass down over such sleeve and tighten sufficiently to rotate the bobbin and wind or twist the thread; but the bobbin will pass on or be drawn off easily, because the diameter of the sleeve is large, and the bobbin will not require to be forced on as tightly to obtain the necessary friction as 1t has to be in cases where the bobbin is thrust upon the spindle, and the bobbin passing over the sleeve to the pulley, or nearly so, lessens the risk of vibration, because the weight is brought as near to its support as possible.

The bolster I is within the bolster-ease. It receives within it the lower part of the spindle E, and around the exterior of the bolster there is a bearing, @whichisspheroidal in its shape, or preferably cylindrical for a short distance say, a quarter of one inch-and then tapering down to the surface of the' bolster, and provided with an oil-channel, h, through said bear- This bearing 'i fits the interior of the bolster-case C, audit is at the line of the pnlA ley G, so that the band acting upon the pulley causes the bearing to press against the ins1de of the case, and the parts are rigidly supported; but the top and bottom of the spindle and the bolsterl are free' and can vibrate in any direction if it is advantageous for them to do so, as under the circumstances before mentioned. The tubular bolster-spring L allows for the said vibration of the bolster and its spindle.

The tubular spring L is between the lower end of the bolster and the bottom of the bolster-case, and being tubular it is kept in position at its bottom end by the case itself without requiring either a hole through or a recess in the bottom of the bolster-case, as in my aforesaid application.

Then the lower end of the tubular bolsterspring Il is flaring, as in Figs. 1, 1l, and 5, the bolster-case can be bored out of the same size to the bottom. If this helical springis of uniform diameter, the lower end of the bolster TOO case can be tapering, as shown in Fig. 3. The friction of this tubular bolsterspring at its lower end against the inside of the case may be availed of' to prevent the bolster rotating; or there may be a notch or hole at 3 for a pin or projection on the spring to enter. Y

The tubular bolster-spring may be made of the cylindrical continuation of the bolster, as seen in Fig. 4, the same being slotted, as seen in the end view, Fig. 6; but I prefer to make such tubular bolster-springof a strip of steel wound upon a mandrel, and of a length to pass entirely through the bolster, as seen in Fig. 5. The portion of this spring that is within the bolster is rigid, being held by such bolster, and only becomes a lining to the bolster. It

'can be pushed or pulled out and replaced with great ease when worn out, and theygroove between one convolution and the next forms an inclined oil-conduit, either to pump up oil when the spindle is revolving in one or else to keep itf'rom overflowing when the spindle is revolved in the other direction. The spindle in this case has to be sufficiently long to reach to the bottom of the bolster-case, or, by preference, the separate step Z is dropped into the tubular bolster-spring, as shown. In Figsl and 3 the stud Z is in one piece with the bolster, and the tubular bolster-spring does not extend u p as high as the bottom end of the spindle. It will now be understood that the sleeve F allows for the bolster-case and bolster rising up within it, the bolster to form a bearing for the spindle, and the case, which preferably rises higher than the top end of the bolster, to form an oilcatcher to receive oil that overflows from the bolster and return it to the lower part of the bolster-case. l

There is au opening at 5 from the oil-cup B in through the bolster-case, and in Figs. l, 3, and 4 there is a hole in the bolster at 6, uto allow oil to pass into the spindle. By this construction I am able to prevent waste of' oil and to supply a sufficient quantity for running a considerable length of time.

If desired, a pin or screw at o, passing into the bearing i, may be used to prevent the bolster revolving.

There is a cover, r, to the oil-cup B, and the same surrounds the bolster-case, and it is provided with a flange, 8. There is preferably a hole through the cover and a notched upper edge to the oil-cup, so that when not in use the dust can be excluded by partially revolving the said cover r.

I claim as my inventionA l. A bolster-case having an oil-cup around it, and the spindle-rail to which the case is secured, in combination with a bolster with an external rounding bearing, i, within the case, a spindle, a tubular sleeve and pulley upon the spindle and surrounding the case, the pulley being near the bearing, and a tubular bolster-spring connected with the lower end of the bolster within the case, substantially as set forth. y

2. The combination, with the bolster, bolster-case, and spindle, of a tubular sleeve attached to the spindle and having a tapering exterior surface to receive the bobbin, and a pulley at the lower end of the sleeve, there being a rigid rounding bearing upon the bollster near the pulley, but within the bolstercase, and a tubular bolster-spring connected with the lower end of the bolster, substantially as set forth.

3. The combination, with the bolster-case and spindle., of' a bolster having an exterior rigid bearing near the middle part of the bolster and fitting the interior of the case and notched for the passage of' oil that may flow over the top of the bolster, and a tubular bolster-spring extending below the lower end of' the bolster, substantially as set forth.

4. The combination, with the tubular bolster-case, of a bolster having an external rounding bearing within the case, a sleeve and pulley, and a helical spring' passing through the bolster and extending below the same to form both a removable lining to the bolster and a spring-support for such bolster, substantially as set forth.

5. In combination with the spindle and bolster, a tubular'bolster-case, ythe interior of which is bored of uniform diameter throughout its length, or nearly so, and a helical spring connected at its upper end to the bolster, and the lower end of such spring being enlarged to fit the interior of' the bolster-case at the bottom thereof', substantially as specified.
